From a1c0050a17f58279480e32b4aa5068282c6982bb Mon Sep 17 00:00:00 2001 From: Lorenzo Pieralisi Date: Wed, 28 Jun 2017 15:13:52 -0500 Subject: PCI: Initialize bridge release function at bridge allocation The introduction of pci_register_host_bridge() kernel interface allows PCI host controller drivers to create the struct pci_host_bridge object, initialize it and register it with the kernel so that its corresponding PCI bus can be scanned and its devices probed. The host bridge device release function pci_release_host_bridge_dev() is a static function common for all struct pci_host_bridge allocated objects, so in its current form cannot be used by PCI host bridge controllers drivers to initialize the allocated struct pci_host_bridge, which leaves struct pci_host_bridge devices release function uninitialized. Since pci_release_host_bridge_dev() is a function common to all PCI host bridge objects, initialize it in pci_alloc_host_bridge() (ie common host bridge allocation interface) so that all struct pci_host_bridge objects have their release function initialized by default at allocation time, removing the need for exporting the common pci_release_host_bridge_dev() function to other compilation units.
